There are a few ways in which you can do this. One of them is to add some
javascript to your code that will listen to onclick and check if your input
button is selected. If it is it will submit the form that initiates your
download. You can also do an Ajax post. Another way would be to create a
link to that view. I don't understand why it needs to be checkbox if it's
not a part of the form the user is submitting.
